I have 2 SIPP accounts configured on my iPhone but when it rings, I don't know which account is receiving the call and consequently don't know how to answer the call.
When I change the ringtone in one account, it automatically changes it to the same one in the other account too.
Is this a bug? Surely you should be able to set different ringtones for different accounts else the setting wouldn't be at account level?
I'm running Zoiper 3.6.1 on iPhone 6, iOS 9.2.1 with Sipgate accounts.
